l invention pertains to enamel coated metal plumbing fixtures such as basins, tubs and 'the like, although in some aspects it is of broader application, itiand more particularly 5" relates to aconstruction for edge portions of suchffixtures etc. whereby-the enamel will takef along such edge portions, adhere thereto and cover the sameuniformly. M

It has beenfound practically impossible to 10"makeavitreousenamelcoating adhere to and cover the edges ofenameled ware so that a uniform coating extending to or covering the edge resulted. No matter how clean the surfaces of the metal to which the enamel is applied,the enamel draws or .creeps back from the edge at different places or thins out to such an extent that the metal is not thoroughly or uniformly covered along such edge.

. Various theories have been advanced as tothe '20 reasons for this action and many attempts have been made to avoid the difficulty, but so far as I am aware, no successful solution has been provided heretofore. f f 7 1 This condition 'isdecidedly objectionable in the case of enameled iron plumbing ware or fixtures, where itis desired not only to have the metal properly covered for protection, but also to present a more sightly and pleas- I ing appearance originally as well as after ggyears of use. There are thereforevboth economic and aesthetic disadvantages in such articles where the metal of the edges is not covered'or uniformly covered by the vitreous enamel coating. l

The unsatisfactory features of enameled ware plumbing fixtures as above related are probably nowhere more 1 objectionable than when they occur about the marginaledges of an overflow or waste orifice or the like inan 4oienameled ware basin or tub,if such overflow or waste 'orlfice be'not covered by a screen or t V strainer or escutcheon plate.- At such" places it is particularly diflicult to get the enamel to adhere properly. If the enamel is thin about -Ithe edges of the openings through which the faucets and waste control mechanisms project, it usually does not matter so much from 7 the standpoint of appearances because es- I cutcheonplates'or the like are ordinarily defiogsigned to cover such defects.

This may be said to be one of the'important objects of the invention.

, Another object of the inventionis topro vide a novel type of constructionfor the formation of an overflow orifice or passage, parso ticularly suitable for wash bowls "or basins, whereby the difficulties of enameling previously encountered are entirely overcome, the

Therefore, wherever it is desired to have the vitreous enamel extend to or about an edge, the edge is rounded as illustrated at 14,15,16317 and 18; Fig. 3 more clearly illustrates the manner in which the edges are rounded and how the enamel 19 adheres to and covers the same,whereas1f the edges were sharp, the enamel would draw or creep,- or would be so thln'in spots'as to provlde an unsightly appearance and to permit corrosion to take place. r
